Chart Normal Distribution

Hey,

I would really much appreciate your help.
I'm trying to build a normal distribution chart, based on data (X and Y axis).
The problem is that I'm getting 1-40 values in the x axis, instead of what I need.
I'm herewith attaching an excel sheet. Please let me know how to solve this.


Thanks,
